INK CARTRIDGE,

Application filed May 21, 1919, Serial No. 298,636. Renewed July 26, 1923.

To all whom t may concern: Be it known that l, BYRON B. GoLDsMrrH,

a citizen ot the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Ink Cartridges; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable'others skilled in the art to which it appertains to ingink by the simple addition of water to the ink-producing materials These have either been contained in special receptacles,Y

or have been in the form ot tablets to be dissolved in water. @t ythese methods the only one which has survived is the ink tablet,

as the former did not produce asuitable ink. rlhe disadvantage of using the ink tablet is readily understood when one considers that to make ink from ink tablets it is necessary to take a measured amount of water for each tabletand place both in a suitable receptacle and agitate until there has been complete solution. In other words, it almostV amounts to as much trouble` in a small way as the manufacture Ot liquid ink does on ak large scale. The consumer becomes the'ink manufacturer. For this reason ink tablets are used very little. The desire to find substitutes for the liquid ink ot commerce,

karises from three disadvantages it has:

Firstly. it is bulky and takes up much space in the factory, on the railroads, and in the dealers stock. Secondly, it is shipped in glass and there is `considerable expense in packing safely, notwithstanding which breakages cannot be avoided. Thirdly, it cannot be shipped in winter as it freezes, ruining the ink or the bottles or both. By the use of my invention it is possible for any unskilled person to produce ink of the finest quality almost instantaneously.

rlhe basic principle of this invention resides in supplying narrow passages for the water wholly or partly lined with ink producing material, which passagesare artificially constructed with such a definite relative proportion between their diameter and length that, as the water passes through them, it necessarily has time to take up the required amount of material to produce la -liquid to dissolve sufficient material, or if the channel is narrow theliquid would flow more slowly and the channelneed not be so long. Y It is a little simpler, however, to employ a number of passages.

The actual proportions of the passages "will, of course, be determined experimentally for each specific type of device placed upon the market, since these will depend (among other things) upon the nature of the inkproducing material and the character of the final ink desired.

The general principle underlying this invention is capable of being carried out in a variety of ways, some of which are set forth in certain copending applications for Letters Patent. There is claimed herein that general Vform or embodiment wherein the ink-producing material is itself channelled or perforated, whether rsuch material be in a singley mass or in separate constituent masses properly assembled,and whether or not the material be associated with a neutral backing for purposes of re-enforcement; also whether the re-enforcement is absorbent or non-absorbent.

A. few of many possible specific embodimentsof the invention hereinclaimed are illustratedin the accomjmtnyingdrawings wherein Figures l and 2 are respectively la vertical section anda plan view of one modification, Figures 3 and l are similar views of'another modification, Figures 5 and `t3 are vertical sections of two further modificationsFigures 7, 8 and 9 are plan views of three Jfurther modifications, and Figure V10 is a transverse sectionof one of the elements used in the form yof dev-ice shown in Figure 9.

It is to be understood that the diameter and length of the channels as shownin the drawings are not supposed to be exact- As alreadystated, theactual diameters and lengths of the passages will be experimentally determined for each particular type of device and character ofink.

In the form shown in Figures' l and 2 there is an external supporting shell l0,- preferably cylindrical, and made of neutral material, such as hard rubber. Within this is located a replaceable mass of ink-produc- 6. An ink cartridge comprising an external supporting shell having an aligning rib, and a succession of perforated ink-produeing dises fitting said shell and each having a depression fitting over said rib.

7. As a means for producing liquid' ink, a network of neutral material having openings of predetermined definite size and proportiens and coated with ink-producing ma- 10 terial.

8. An ink cartridge having passages for the free flow of liquid, the Walls of which contain ink-producing material.

9. An ink cartridge consisting of ehanneled ink-producing material for the passage of liquid.

l0. An ink cartridge having an inlet and an outlet opening communicating with each other by means of passages, and ink-produeing material in said passages.

In testimony whereof, I aliix my signature.

BYRON B. GOLDSMITH.
